Description

Stopper for peritoneal placement of intra-abdominal drainage tube

The present invention relates to a stopper for fixing a drainage tube inserted into the abdominal cavity to maintain the peritoneal position without falling out for drainage of inflammation and pus from the abdominal cavity after a surgical operation.

In the case of a medical drainage tube used during surgery, it is connected to a drainage device, such as a hemo bag, and is used as a passage for discharging bodily fluids that may occur during surgery from an inserted surgical site to the outside.

Since these medical drainage tubes are directly inserted into and connected to the patient's body, operators form a knot in the drainage tube using surgical sutures and fix it in order to minimize the flow of the drainage tube and prevent detachment.

However, such a conventional fixing method is directly fixed by forming a knot in the main pipe of the drainage pipe using a suture or the like.

The strength and fixing force of the knot made by the operator, and the time of the operation are very different depending on the skill level of the operator.

Due to this, when an unskilled operator fixes the drainage tube, the suture is too strongly knotted in the drainage tube, and the diameter of the drainage tube is reduced to an extent that hinders the discharge of bodily fluid.

In addition, it is too weakly knotted to cause a problem with the fixing force of the drainage tube, and thus easily has fluidity by an external force, thereby causing various problems to the surgical site of the patient.

An object of the present invention is to simplify and stably install a drainage tube for draining blood and pus from the abdominal cavity to the outside of the abdominal cavity.

The present invention relates to a drainage tube inserted into the abdominal cavity through the peritoneum of a surgical patient and drained to the outside of the abdominal cavity; and a guide member approaching the outer surface of the peritoneum along the drainage tube and coupled with the guide member anchored at the incision site to be tightly fixed around the incision site.

The guide member is a pipe-shaped guide tube formed with a first hollow hole into which the drain tube is inserted, and has a chain body caught on the outer surface of the drain tube on one side and an anchor body anchored around the inner surface of the peritoneum on the other side. It is provided.

The induction member has an inlet formed in the first hollow hole to be formed with a diameter smaller than that of the drain pipe, and an outlet to be formed with a diameter of the drain pipe, but the inlet is formed obliquely in the first hollow hole to form the drain pipe. A low jaw is formed by tightening the outer surface of the exit, and an uneven jaw inserted into the incision of the peritoneum is formed on the outer surface of the exit.

The anchor body is composed of a diffusion band and a support member that are expandable and variable around the incision in the abdominal cavity by a fixing member coupled when the drainage tube is placed, and a bending groove for expansion and change is formed between the diffusion band and the support member. are provided

The fixing member is formed with a second hollow tube inserted into the drainage tube exposed to the outside of the peritoneum, enters the inside of the incision from the outer surface of the peritoneum and is coupled with the guide member, and is in close contact with the outer surface of the incision in the peritoneum. It consists of a head and a gripping tube that grips and presses the head so that it comes into close contact with the outer surface of the incision site.

In the fixing member, a concave-convex groove engaged with the concave-convex jaw of the anchor body is formed on an inner diameter of the cap body, and a release piece for disengagement from the anchor body is protruded in the longitudinal direction from the gripping pipe.

In the gripping tube, an incision is formed from the protruding position of the release piece to the ends of the head and the cap body.

The incision line is narrowed while being inclined toward the head position on both sides of the width of the release piece, and is formed with a constant width from the head to the cap body to form a “Y” shape.

The head is formed with a diameter covering the periphery including the incision site, is provided with an adhesive layer adhered to the periphery including the incision site when in close contact with the outer surface of the incision hole, and is sealed with a material that absorbs moisture to a diameter smaller than that of the head. Fees are provided.

In the present invention, the mounting state of the drainage tube for draining the blood remaining in the abdominal cavity or pus that may occur outside the abdominal cavity after abdominal surgery is simple without the need to sew around the incision site and the drainage tube with an induction member and a fixing member of an interlocking structure provided in the drainage tube. it is done

The removal of the drainage tube can also be solved simply by releasing the interlocking structure, thereby facilitating medical work and providing high-quality medical services to patients.

In the present invention, in order to be inserted into the abdominal cavity through the peritoneum of a surgical patient and drained to the outside of the abdominal cavity, a stopper having a configuration for easily and simply fixing the drainage tube 90 to the patient's peritoneum during the procedure is used.

The stopper of the present invention is formed of the same material as the drain tube 90 and enters the abdominal cavity while being mounted on the drain tube 90 located inside the abdominal cavity and is anchored around the incision in the peritoneum P so that the drain tube is in the peritoneum It includes an induction member 200 to be mounted.

It is composed of a fixing member 300 that approaches the outer surface of the peritoneum P along the drainage tube 90 and is combined with the guide member 200 anchored at the incision site S to be tightly fixed around the incision site.

The induction member 200 is a pipe-shaped induction pipe 210 at one side of the induction pipe 210 in a state in which a first hollow hole 220 into which the drain pipe 90 is inserted is formed. A chain body 230 is formed on the outer surface of the drain pipe 90 in a tightened state.

The other side is provided with an anchor body 240 anchored around the inner surface of the peritoneum.

In forming the first hollow hole 220 formed inside the center of the induction pipe 210, the inlet 221 is formed to have a smaller diameter (d) than the diameter (D) of the drain pipe 90, and the outlet 223 ) is formed as the diameter (D) of the drain pipe (90).

The inlet 221 is formed obliquely in the first hollow hole 220 so that the lower jaw 232 is formed by tightening the outer surface of the drain tube and is caught, and the outer surface of the outlet 223 has an incision (S) of the peritoneum (P) To be inserted into the concave-convex jaw 250 is formed.

Since the diameter (d) of the inlet 221 of the induction pipe 210 is smaller than the diameter (D) of the first hollow hole 220, the blocking jaw 232 formed has an inclined shape. The tip of the jaw 232 presses while tightening the surface of the drainage tube 90 .

The restraining jaw 232 serves to maintain a stable fixed state in a state in which the induction tube 210 is mounted on the drainage tube 90.

With the drain tube 90 inserted into the abdominal cavity, the outlet 223 of the guide tube 210 of the guide member 200 moves through the peritoneum P by pulling the drain tube 90 exposed to the outside of the peritoneum P. It is in a state of being inserted into the incision site (S).

When an attempt is made to place the drainage tube 90 on the peritoneum P, the anchor body 240 of the guide member 200 mounted on the drainage tube 90 is changed by the fixing member 300 to A configuration that allows expansion and contact around the incision site (S) is required.

Therefore, the outer circumferential surface of the guide tube 210 is partially incised and removed to form a diffusion zone 243 and a support zone 244 that are bent and unfolded like the ribs of an umbrella, extending between the diffusion zone 243 and the support zone 244. A bending groove 241 that can be bent for variableness is provided.

The stopper is provided with a fixing member 300 that is coupled to the induction member 200 when the peritoneum P of the drainage tube 90 is mounted and disengaged from the induction unit 200 when the stopper is released.

The fixing member 300 includes a cap body 310 that enters the incision site S from the outer surface of the peritoneum P and is coupled with the guide member 200 .

A head 330 in close contact with the outer surface of the incision of the peritoneum P and a holding tube 320 that grips and presses the head 330 to adhere to the outer surface of the incision S are formed, A second hollow tube 321 inserted into the drain tube 90 exposed to the outside is formed.

Concave-convex grooves 312 engaged with the concave-convex jaws 250 of the anchor body 340 are formed on the inner diameter of the cap body 310 formed in the fixing member 300 .

A release piece 340 for release from the coupling with the anchor body 340 protrudes from the gripping tube 320 in the longitudinal direction, and the release piece 340 extends from the gripping tube 320 to the head. 330 and the end of the cap body 310 so that the incision 342 is formed.

When the release piece 340 is pulled, the surface of the gripping pipe 320 is cut to a depth that can be cut, and the width of the release piece 340 is inclined toward the head 330 position on both sides of the release piece 340 to form the incision line 342. It gradually narrows and is formed with a constant width from the head 330 to the cap body 310 to form a “Y” shape.

The head 330 is formed with a diameter covering the periphery including the incision site (S), and is provided with an adhesive layer that adheres to the periphery including the incision site (S) when in close contact with the outer surface of the incision site (S). , The sealing band 331 is provided with a smaller diameter than the head with a material that absorbs moisture.

4 is a cross-sectional view showing a state in which anchoring is attempted after the drainage tube is inserted into the abdominal cavity in a state in which the drain tube is mounted on the peritoneum with the stopper of the present invention, and FIG. 5 is a cross-sectional view showing the coupling state of the fixing member in the stopper anchoring state.

According to FIG. 4, the stopper 100 of the present invention is performed while the induction member 200 is attached to the drainage tube 90 to be inserted into the abdominal cavity.

The drainage tube 90 is inserted through the incision S of the peritoneum P so that the guide member 200 penetrates the incision S of the peritoneum P and enters the abdominal cavity.

The second hollow hole 321 of the fixing member 300 is inserted into the drainage tube 90 located on the outer surface of the peritoneum P, and the fixing member 300 is moved toward the outer surface of the peritoneum P so that the cap body 310 is incised. Press to insert into (S).

Then, when the fixing member 300 is pressed while pulling the drainage tube 90, the guide tube 210 of the guide member 200 is inserted into the incision S of the peritoneum P in the abdominal cavity through the outlet 223. and is coupled with the cap body 310.

When the outlet 223 of the induction tube 210 is inserted into the incision S on the abdominal cavity, the tip of the lower jaw 232 formed at the inlet 231 of the induction tube 210 is on the surface of the drainage tube 90. When pulling the drainage tube 90 by tightening and digging into a small diameter (d), it enters the incision (S) of the peritoneum (P).

The coupling of the outlet 223 of the induction pipe 210 to the cap body 310 occurs when the concave-convex jaw 250 formed on the outer surface of the outlet 223 engages with the concave-convex groove 312 formed in the inner diameter of the cap body 310. possible through the structure.

In particular, when the concave-convex jaw 250 of the outlet 223 of the induction tube 210 and the concave-convex groove 312 of the cap body 310 are coupled, the operation of pressing the fixing member 300 toward the abdominal cavity while pulling the drainage tube 90 At the same time, meshing coupling is achieved.

When the head 330 of the fixing member 300 comes into contact with the outer surface of the peritoneum P, the sealing band 331 is adhered to the outer surface of the incision S by an adhesive layer and inserted into the incision S. The gap around the 310 is blocked.

It absorbs and blocks leakage of liquids such as residual blood and pus due to its moisture absorption properties.

The concave-convex jaw 250 of the guide tube 210 inserted into the incision S of the peritoneum P in the abdominal cavity and the concave-convex groove of the cap body 310 inserted into the incision S from the outside of the peritoneum P In a state in which 312 is engaged and coupled, the operator pulls the drainage tube 90 while further pressing the gripping tube 320 of the fixing member 300, which is similar to an operation of opening an umbrella.

When the drainage tube 90 is pulled, the guide tube 210 undergoes an operation in which the anchor body 240 is variablely diffused by the force that is pulled to the outside of the peritoneum P.

That is, as the bending groove 241 of the anchor body 240 is bent by the pulling force, the diffusion band 243 and the support 244 are deformed into a cone or mushroom shape, forming a wide diameter as shown in FIG. 5 to form a peritoneum (P ) is brought into contact with the inner surface of the incision site (S).

As such, by pulling the drainage tube 90 and pressing the fixing member 300 toward the peritoneum P, the diffusion zone 243 and the support 244 of the anchor body 240 are wider than the sectional area of the guide member in the abdominal cavity. It forms an anchoring action that occupies the area.

Since the concave-convex jaw 250 of the outlet 223 and the concave-convex groove 312 of the fixing member 300 maintain an engaged state while contacting the incision site S, the drainage tube 90 is placed on the peritoneum P. Since the state is maintained stably, measures for fixing the drainage tube 90 after surgery are solved very simply.

As such, when the drainage tube 90 is fixed to the peritoneum P with an easy operation and the purpose of use is achieved, when the drainage tube 90 is removed, it is solved by pulling the removal piece 340 of the fixing member 300.

6 shows a plane of the anchoring state of the stopper of the present invention, and FIGS. 7 to 10 show the removal state of the release piece for removing the drainage tube fixed to the peritoneum by the stopper of the present invention.

The release piece 340 protrudes from the gripping tube 320 of the fixing member 300 exposed to the outer surface of the peritoneum P, so when removing the drainage tube 90 from the abdominal cavity, hold the release piece 340 as shown in FIG. pull

When the operator pulls the release piece 340, the incision line 342 formed from the release piece 340 to the gripping tube 320 and the cap body 310 is cut along.

As shown in FIG. 8 , the gripping tube 320 , the head 330 , and the cap body 310 are cut and widened, and at the same time, the coupling state between the uneven jaw 250 and the uneven groove 312 is released.

In this way, when the engagement state between the concave-convex jaw 250 of the induction member 200 and the concave-convex groove 312 of the fixing member 300 is released by removing the release piece 340, the fixed state of the drain pipe 90 is released, and FIG. 9 As such, the drainage tube 90 can be pushed into the abdominal cavity.

When the drain tube 90 enters the abdominal cavity due to release of the fixation of the drain tube 90, the diffusion zone 243 and the support 244 of the anchor body 240, which have been variable in diffusion, return to a horizontal state as shown in FIG. 10.

When the diffusion zone 243 and the support zone 244 of the anchor body 240 return to the horizontal state as shown in FIG. 10, fixing force is not provided, so when the drainage tube 90 is pulled outward to the peritoneum P, the guide member 200 The drain tube 90 equipped with is brought out of the peritoneum 90.

The drainage tube 90 is separated from the abdominal cavity, and the removal of the drainage tube 90 is completed by stitching the incision S of the peritoneum P.
